IPC: G01L1/22
Filed: 1952-07-02
Abstract: 723,370. Resistance strain gauges. JONES, H., and BRITISH CELANESE, Ltd. June 30, 1953 [July 2, 1952], No. 16655/52. Class 40 (1) A woven-ribbon type strain gauge for use at elevated temperatures consists wholly of wire and other heat-refractory material. The ribbon, Fig. 1, comprises a warp of glass fibre yarns 4 woven in a plain weave with a weft 5 consisting of a resistance wire 7 braided with four glass-fibre yarns 8. After weaving, the ribbon is annealed, by raising it to a temperature of 400‹C. approxmately and then slowly cooling, to prevent the weft from springing out of position when the ribbon is cut into lengths to form strain gauges which are secured to the articles to be tested by a heat-resisting cement, e.g. Quigley's Blue 1925 Cement. Alternatively, the weft may be bare wire, the warps and the cement being relied on for insulating purposes. To facilitate weaving in such a case, the wire may be initially. covered with a lapping of cellulose acetate yarn which is dissolved from the woven ribbon by acetone. The resistance wire used is less than 0.0032 inch diameter and may be of nickel-chrome alloy. Fibreglass glass yarns, or, for higher temperatures, the continuous glass yarn known as " Refrasil " may be used. As described in Specification 647,377, [Group IX], the ribbon may be woven in sections Fig. 2, at each end of which a projecting loop 9 of the wire containing weft is formed at the ribbon edge to serve the attachment of terminals when the ribbon is cut at 11. Specification 623,641, [Group IX], also is referred to.

Race games, mechanical.-Relates to a race game in which model horses 14, Fig. 1 are supported by a square spindle 13 rotatably mounted on carriages 11 each having four wheels 12 bearing on a wood'en track 6. Each carriage is attached to an endless cord 16, which is driven by a pulley 21 mounted on a spindle 20 having a handle. The tension in the cord may be adjusted by moving the pulley brackets 19, and is kept sufficiently low to allow the cord to slip round the pulley when the carriage is checked. The tracks 6 are of an undulating nature to make the horses appear to jump obstacles 5. The horses are reversed at each end' of the course bv a sector 15 rigidly mounted on the spindle 13 engaging with a rack 15<a>, Fig. 3. The rack consists of three ordinary teeth e and one slightly longer pivoted tooth f attached to a plate i adapted to bear on a spring j at one end and on the base-plate at the other. Thus when the sector moves from left to right it is turned through 180‹, but on the return journey, the tooth f pivots and no rotation occurs. A locking-mechanism comprises a number of brackets 29 attached to a slidable rod 26 and adapted to surround each of the spindles 13. The mechanism is held in the open position by a leaf spring 32 engaging a slot 31 in the rod 26. Each of a series of crank-levers 33 comprises two arms a, b, of which the arm a is adapted to engage its corresponding spindle 13, while the arm b actuates an indicator 37 and engages a pin 35 on a slidable rod 36, the movement of which causes the spring 32 to release the bar 26. Thus the winning horse actuates its own indicator and prevents the rest of the field from reaching the post.

Title: Dynamometers
IPC: G01L3/14
Filed: 1963-04-30
Abstract: 1,091,411. Dynamometers. PRODUCTION ENGINEERING RESEARCH ASSOCIATION, T.M. Birchall and R. St. John Richards. April 27, 1964 [April 30, 1963], No.17022/63. Heading G1W. [Also in Division F1] In a hydraulic dynamometer comprising a hydraulic pump or motor having its outer casing supported in anti-friction bearings in a stationary housing so that the casing is free to rotate against the constraint of a torque-measuring linkage, communicating ports or passages are formed in the casing and in the stationary housing such that the amount of rotation of the casing is determined only by the rotation of a shaft whose torque is to be measured and not by the movement of the fluid. As shown, a barrel 28 (Fig. 1) forming part of the hydraulic pump or motor transfers rotational movement of a shaft 26 to the outer casing 17 through axial pistons 31 and a swash plate 24. The movement of the casing 17 relative to a stationary end ring 15 of the stationary housing 12 in conjunction with strain gauge links 25 indicate the torque of the shaft 26. According to the direction of rotation of the shaft 26 and to the mode of operation of the dynamometer i.e. motoring or absorption dynamometer, the fluid is circulated to the pistons 31 from a hydraulic circuit via two ports 38, 53. The pistons are supplied with fluid from inlet port 38 through a radial duct 39 which leads to an annular groove 41 on the inner surface of a cylindrical fitting 13 at one end of the stationary housing 12. A duct 42 in an end fitting 18 of the casing 17 directs the fluid to a kidney-shaped passage 43 which is positioned to feed the rotating pistons successively with fluid while another duct 46 leads fluid from a kidney-shaped passage (45) Fig. 2 (not shown) which is positioned to drain the rotating pistons successively. The duct 46 opens into a central space 47 which directs the fluid to the outlet 53 by radial ducts 48 and an annular passage 51. In further embodiments, the annular passages 41, 51 may be formed at the end of the ducts 42, 48 in the surfaces of the end fittings 18, and 19 respectively and instead of providing an annular groove 41 having a duct 39 leading to a duct 42 the dynamometer may be provided with several circumferentially spaced radial ducts (39) each leading to a corresponding duct (42) Fig. 8 (not shown). The pump or motor is supported either by ball, roller or needle bearings or by fluid bearings and the speed of rotation of the shaft 26 may be sensed by a magnetic pick-up head 59.

Title: Process for producing coke
IPC: C10B55/02
Filed: 1925-07-02
Abstract: 255,620. Trumble, M. J. July 2, 1925. Coking processes.-Coke is obtained from coal, lignite, peat, or wood by heating the material in a retort and distilling off the volatiles by the passage of superheated steam or hot vapours, the hot porous residue being treated with a liquid hydrocarbon and the temperature being so maintaned that the latter is cracked and carbon deposited on the coke. The vapours or light oils are condensed and the incondensable gases are used as fuel. The material is charged into a retort 11 heated by burners 13 and having a a steam pipe 25, a liquid hydrocarbon pipe 31 leading to a ring of perforations 32, a drain pipe 26, and a vapour outlet pipe 36. As soon as the charge is sufficiently heated by the burners 13 superheated steam is introduced by the pipe 25 and drives off the volatile from retort A, Fig. 2, into the vapour pipe 36 of a retort B down which they pass to the drain pipe 26 and so through retorts C and D to a condenser 46. A further retort E is meanwhile being charged. When the charge in retort A is freed of its volatile content, a liquid hydrocarbon is injected through pipe 31 and is cracked to produce vapours which are passed through retorts B, C and D to the condenser 46. Retort A is then cut out and retort E added to the series, the necessary connections being made to the condenser 46. The supply of steam may be continued during the injection of the hydrocarbon.
